Application led January 31., 1927. Serial No. 164,862.

This invention relates to `window constructions 1n whlch one of the window sections are adapted to be moved u p and downA fwhen desired. Attached to`this movable U section of the window is a foraminous screen, which is mountedd on a suitable roller hereinafter explained in detail.

The vobject is to provide a means for automatically positioning, the screen in the win l@ dow opening when the movable section of the window is moved to cause an opening.

A further object is to provide a covering for the rollery and screen,which covering will also act as -a positioner and tightener l5 for the drawn up portion of the foraminous screen. i

With the foregoing and other objects in viewjas will appear as the description proceeds, the invention consists ein the novel 29 construction, combination and arrangement or co-operating elements as hereinafter more specically set forth, claimed and shown in the accompanying drawings forming a part n@ of the present application, in which: i

ing open position and the foraminousscreen pulled up across such opening'.

Fig. 2 is an end View showingthecovermi ing for the roller andv the oraminous screening. v

Figl is a sectional view showing the interior parte of the roller, part being broken awa A 171g. 4 is a .sectional view showing a portion of the cover plate member and one end of the holder members. `Like numerals of reference designates corresponding parts t-hroughout the diiferent ce views.

rllhis construction can be used in connection with practically any form of window wherein either the top or bottom sections are movable up and down., l haveshown in e5 Fig. 1 of the drawings, the screen attached to the lowersection of the window, but it `might be attached to the uppersection by merely reversing the positionot the same relative to the movable yupper portion and 5o attaching the screen to the upper part of the frame.

At each side of the window frame, I provide a channel guide 5 in which the opposite sides of the foraminous screen 6 will move up and down. These guides 5 will alsovact as a means -for providing e. tight closure be-v Fi 1 is a plan view of a window showr-V e movable section moved to partially t tween the screen 6 and the side of the window frame, so that thetiies andother insects Will not be able to find their way in between the screen and frame.

7 .indicates a roller on which the screen is rolled when in its normal closed position. When the roller is being cut out of fiat metal, lugs are .provided at the opposite ends so that When the roller is shaped-into a cylindricalshape, these lugsv are positioned diag? onally opposite each other and are bent towards the centre in the position as noted at 8. The inner ends Iof these lugs are provided with annular openings 9 registering opposite each other. Spaced a distance from the end,

yI provide a snugly fitting disc 10. Between the disc 10 and the lugs 8, 1 provide a tension roller 11 provided with a recoil spring 12. One end of this recoil spring is secured te through the'roller 11 as at 14 while the other end is secured toone of the lugs 8 as at 15. 16,V is an end bracket provided with aninwardly formed portion adapted to operate in conjunction with the lugs 8, the end of the bearing pin from the roller 11 extends through an opening in this inwardly formed portion and is retained therein against turning. c I

The roller 7 is provided with two cylindrical sections one or both of which may telescope over a central cylindrical section 17. One of the end sections 7 ymay have a tight fitting with the central section 17, while the other end section may be moved relative theretoh so as to provide a wider or narrower'roller to lit the desired openin The central section 17 is provided wit spaced indentations 18 into which a keeper 19 is adapted to engage, which keeper is end of the telescopic cylindrical section 7. lt may be found that wider screens are desiredand by having -a roller of the type hereinbefore described, it will not? be necessary to go to the eXtra .,eXpe`nse of providing rollers, as a new-fl. screen the desired width can be easily attached to the roller when it is lengthened the'desired length.

. 2O indicates a curved metalA plate pref-i erably having a rolled back front edge'21`.

This metal plate 20 is fittedibetween the end plates 16, which end plates are securely screwed to the window frame by the screws 22. The plate 16 carries inwardly directed pins 23, 24 and 25. rlhe pin25 extends inwardly and acts as a pivotal pin for the lill@ lower rolled edge 26.

other presses against the curved metal plate 20. This spring 27 presses the plate 20 so that its upper portion will normally rest against the pins 24 in the opposite end plates 16. The -rolled edge 21 will protrude outwardly a sufficient distance so as to align the pulled out portion of the screen 6 with the path of travel of the movable section of the window. The curved plate 2O will form a neat cover fitted over the screen when rolled up on the roller either on the sill or on the upper portion of the frame.

rlhe foregoing specification andv annexed drawings disclose the preferred embodiment of my invention, but it is to be understood that minor changes may he resorted to in revenez the commercial adaptation of my invention without departing from the scope of the invention as hereinafter claimed.

Vhat l claim as new is:

In .combination with a roller screen mounted in end plates secured to a windowl sill; the end of said screen having cont-act with a movable' sash frame, aguide plate for directingAV said screen to and from the ath of travel of said frame; said plate eing pivotallj)7 Connected to said end plates; means for pressing said plate towards said screen and a means carried by each of said en'd plates to limit' the downward movement of said plate under said tension.

ln testimony whereof, l aix my signature.
